FOUNTAIN MARKING-BRUSH,

SPECIFICATION forming partof Letters Patent Not 702,286, dated Jui-le 1O PATEN Application filed December 6, 1901. Serial No. 84,798. (No model- X r To all whont it U ility-(3077106777,:

Be it'knownthat I, JESSE A. CRANDALL, a citizenof the United States, residing in the borough of Brooklyn, county of Kings, and

5 State of New York, have invented certain new and useful Improvements in Fountain Marking-Brushes, of which the following is a specification, reference being bad therein to the accompanying drawings, in which-- Figure 1 is a longitudinal sectional view of the brush; Fig. 2, a side elevation thereof,

and Fig. 3 an enlarged sectional view of the brush end of the device.

The object of this invention is to provide,

.asimple devicewhich may be used for markingshipping cases and packages and which will carry within itself a supply of markingink or other marking fluid.

Another object of the invention is to provide means whereby the flow of marking fluid to the brush may he controlledthat is, increased or diminished or entirely cut oil? from the brush. a Another object of the invention is to so construct the brush that its parts may be readily separated for the purpose of cleaning, the body portion of the brush being shaped in such a manner that there will be no shoulders on its interior for the lodgm'ent 0 of sediment.

1 Referring to the various parts by numerals, 1 designates the hollow body portion of the device, which is formed with the narrow upper part or handle 2 and the enlarged bulblike lower portion 3, the walls of the lower;

half of the bulb-like portion inclining inwardly and downwardly, as shown, the whole of this body portion forming a reservoir,withinwhich is contained the marking fluid. To

0 the lower contracted end of the body portion is screwed the brush-head 4, the interior of the body portion being threaded to receive the threads formed on the exterior of the brush-head. In this head, below the threads 5 thereon, is formed an annular groove or channel 5, in which is placed apacking-ring 6, upon which bears the lower edge of the body portion, thereby forming a liquid-tight joint. Formed integral with the brush-head is a ra- 5o dial flange 7 ,whose cylindric surface ismilled to furnish a roughened. part, which may be readily grasped by thefinger s and the lei-dens head unscrewedfrom the b'ody porti ojni" in this head is formed a;cen tral "longitudinal. channel or passage 8, whose upper portion I flares, the upper end of this passage being equal in diameter to the diameter of theinteriorot the body portion-at this'pointin order that there shall be no shoulders at the upper end of the-brush-liead fonthedodg- 6o ment of sediment.- Secnred to'tlie lower (and of the brush-head and surroundinglthepas sage therethrough is'the hrn'sir'i), whichn ay be-of a suitable size andicrnioest adapted for the purposes for whichthisde'viceisdesigned.

Extending longitudina though the res-" ervoir is a valve-rod it in; e lower'endof which is formed a conierifi'valve -1l,which seats in the flaring upperendof the passage 8. The w'alls'of the flared pnriionbf'theipassage 8 are convexed, so that'the valve lit-seats, on a curved surface. i heipurposeof this is that should the long valve-rod be fleiiedor bent when forcing the valve to "its seat the valve may assume a slightly-distorted; or inclined position with respectto the c'ential passage 8 without destroying the liquid-tight joint between the valveand the valve-seat.

On the upper end of the valve=rod secured 8o a closure-cap 12, which is exteriorlythreaded and is adapted to engage threadsformedon the interior of the reservoir atthe upper end of the narrow portion 2. fA-radialflange is formed on theupper end of this cl sure-ca the cylindric surface of whichds milled in order that it may be securely grasped when screwing the cap into the body part ofthe dc vice. r The operation of the device will be obvious from the foregoing description and may be briefly set forth as i'ollvw's: The reservoir is filled with the marking fluid and the valve is inserted therein and the cap 12 screwed into place sufliciently to cause the valve to enter 5 the passage 8 and seat on the rounded waii of the flaring portion of said passage. A vent 13 is formed near the upper end of the narrow portion 2 of the reservoir and is so located that when the cap 12 is screwed in suf- 10o ficiently to cause the valve 11 to close the passage 8 the vent will he closed by the inner end of the cap 12, but when .the capis un-' screwed to raise the valve from the seat the vent will be uncovered. The extent of the uncovering of the vent will be dependent upon the extent of the opening of the valve, so that when the valve is fully open the vent will be correspondingly open and when the valveis only slightly open the vent will be slightly uncovered. In this way aneven flow of the marking fluid is assured through the passage 8 to the brush.

The reservoir may be filled by removing the brush-head and leaving the valve and cap in place. The valve-rod is made shorter than the reservoir, so that when the brushhead is removed the valve will be protected by thereservoir and will not be in danger of being bent or broken. Another advantage of this structure is that as the brush-head is screwed into the reservoir the flared portion of the passage 8 will center the valve.

It will be readily understood that a marking-brush of this design will. be invaluable to shipping-clerks and others desiring to mark a great many packages for shipment or for any other-purpose. The peculiar shape of the device makes the same convenient for handling and the provision of the valve and the cap for positively moving the valve is of importance in that it will prevent the leakage of marking fluid out through the brush when the brush is not being used, a simple turn of the cap 12 being snfiicien-t to effectually seal the passage 8. The peculiar shape of the reservoir is also of great advantage in thatit may be thoroughly cleaned by removing the cap 12 and the valve attached thereto and also the brush-head and permitting water to flow therethrough. It is also important that the inner surface of the walls of the lower portion of the bulb-like part 3 of the reservoir should incline inwardly and downwardly and that there should be no shoulder at the junction of said walls with the upper end of the wall of the flaring part of the passage, 8 in order that the fluid will readily flow down the walls of the bulb-like part 3 into the passage 8, every drop of liquid'being thus permitted to flow t0 the brush.

An important feature is the annular flange externally milled. The object ofthis construction is not only to provide an efiective liquid-tight joint, but also to aiford a convenient means for removing and, replacing' the brush-head, the milled flange-being at a position sufliciently remote from the brush to avoid soiling the fingers in manipulating it. It will be readily understood that, if desired, an independent filling-opening may-be formed in the reservoir 'ata suitable point and that a suitable liquid-tight closure may beprovided therefor in order that the reservoir may be filled while the valve is-closed.-

Having thus described my invention, what- I claim as new, and desire to secure by Letters Patent, is p 1 In a marking-brush, the combination of a tubular reservoir open at its ends and internally threaded at each end and provided at its upper end with a lateral vent 13, a brushhead externally threaded and screwedinto the lower endof the reservoir and provided with a central passage leading to thebrush and flared upward and: outward at its upper end, said'brush-head being provided with an annular groove or socket 5 below its threaded portion to receive the lower end of the reservoir, said groove or socket forming an;anuu-*- lar upwardly-extending flange 7'fitting and embracing the lower end of the reservoir, the external surface of this flange being milled, a packing-ring in the annular groove, an externally-threaded cap screwed into the upper end of the reservoir and adapted to open and to close said vent 13, a valve-rod secured to this cap and carrying a tapered valve at its lower end adapted to seat in the flared passage of the brush-head, as and for the purposes set forth.

In testimony whereof I hereunto affixmy I signature, in the this 2d day of December, 1901.
